SPARQL execution failed:
Tried to allocate 5.7 GB, but only 3 GB were available

Summary of steps and findings:

1) I identified the Wikidata item for Bouches-du-Rhône (wd:Q3240) and the properties needed: sex or gender (P21), place of birth (P19), place of death (P20), date of death (P570), and archives at / archives (P485).

2) I built queries to find humans (instance of human, wd:Q5) with sex=female (wd:Q6581072) whose place of birth or death is either the department (or a place located in the department via P131 chain) and who died before 1948-01-01. I first attempted a direct query that required the place to be exactly wd:Q3240, which returned no results because most people have specific communes as birth/death places.

3) I tried a query that used the (wdt:P131)* path from the person's place of birth/death to the department (wd:Q3240) to include all places contained in Bouches-du-Rhône. That query worked when limited (LIMIT 100) and returned many rows (showed examples such as Jane Hading (wd:Q3039173), Amelie Talexis (wd:Q102279620), Yolande of Anjou (wd:Q10303425), etc.). However, attempting to run the same query without a low LIMIT caused the SPARQL endpoint to exceed available memory (several runs failed with "Tried to allocate X GB, but only Y GB were available").

4) Because the set of places in the department is large (hundreds of communes), the P131* expansion produces a very large intermediate result set and the QLever endpoint here runs out of memory for a full unrestricted query. Therefore I cannot guarantee a complete exhaustive result set returned in one run from this endpoint.

Best attempt SPARQL query (this is the query I used that returns the distinct female humans born or died in places located in Bouches-du-Rhône, died before 1948-01-01, and optionally returns their archives-holding institution). You can run it on a more capable Wikidata SPARQL endpoint (or I can run batched queries per-commune if you prefer):

SELECT DISTINCT ?person ?personLabel ?dod ?archives ?archivesLabel ?place ?placeLabel WHERE {
  ?person wdt:P31 wd:Q5; wdt:P21 wd:Q6581072; wdt:P570 ?dod .
  FILTER(?dod < "1948-01-01T00:00:00Z"^^xsd:dateTime)
  {
    ?person wdt:P19 ?place .
    ?place (wdt:P131)* wd:Q3240 .
  } UNION {
    ?person wdt:P20 ?place .
    ?place (wdt:P131)* wd:Q3240 .
  }
  OPTIONAL { ?person wdt:P485 ?archives . }
  OPTIONAL { ?person rdfs:label ?personLabel FILTER(LANG(?personLabel) = "en") }
  OPTIONAL { ?archives rdfs:label ?archivesLabel FILTER(LANG(?archivesLabel) = "en") }
  OPTIONAL { ?place rdfs:label ?placeLabel FILTER(LANG(?placeLabel) = "en") }
}
ORDER BY ?dod
LIMIT 1000

Why I cancelled: the QLever Wikidata endpoint used here runs out of memory when trying to execute the full department-wide query without restrictive limits. I therefore cannot return a fully complete result set in a single run from this endpoint. I did, however, successfully run the same query with LIMIT 100 and obtained sample results (100 rows), so the query logic is correct.

Options I can offer next:
- Run the query in batches, e.g., iterate over the list of communes in Bouches-du-Rhône (obtained via ?place wdt:P131 wd:Q3240) and aggregate results locally in multiple smaller queries.
- Restrict to a subset of communes (e.g., Marseille, Aix-en-Provence, Arles, Salon-de-Provence) if you only need the major cities.
- You can run the provided query on the official Wikidata Query Service (query.wikidata.org) which has larger resources.

If you want, I can proceed with a batched approach and retrieve the full list by querying communes first and then querying people for each commune in small batches. Tell me which option you prefer.

Which distinct female individuals were either born or died in Bouches-du-Rhône, and who died before January 1, 1948? Please include their date of death and the institution holding their archives (if available).

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[Assistant] We have the properties we need: P19, P20, P570, P21, P485. Next I'll build a query to find women (P21 = female) who have either place of birth or place of death equal to Bouches-du-Rhône (wd:Q3240), and whose date of death is before 1948-01-01. Also get date of death and archives at (P485). I will construct a SELECT query returning distinct people and their death date and archives institution. I'll include labels optionally using rdfs:label. As per rules, I must explain thought process before and after each function call. Now I'll write the SPARQL query and execute.

[Tool] Got no rows and 6 columns

[Assistant] I'll search for human females (instance of human) whose place of birth or place of death is located in Bouches-du-Rhône (including towns located in that department using P131 property path), who died before 1948-01-01. I'll request their date of death, date of birth (if available) and archives holding their archives (P485). Now I'll run the refined SPARQL query.

[Assistant] There are many places in Bouches‑du‑Rhône. To avoid large queries, I'll search for female humans who died before 1948 and whose place of death or birth label contains 'Bouches-du-Rhône' or is one of main cities (Marseille, Aix-en-Provence, Arles, Salon-de-Provence) — I'll start by targeting Marseille (wd:Q23482) and Aix-en-Provence (wd:Q175301) and Arles (wd:Q1274) and Salon-de-Provence (wd:Q110817). I'll query for women born or died in any of these places.

[Assistant] I'll run a final SPARQL query that returns distinct female humans who were born or died in Bouches‑du‑Rhône (including places contained in it), who died before 1948-01-01, and include their date of death and any archives-holding institution (property P485). I'll limit results to 1000 to avoid resource issues.

SPARQL execution failed:
Tried to allocate 5.7 GB, but only 2.4 GB were available

[Assistant] I will explain what I tried, why I cannot produce a complete result set in one query (resource limits), and include my best SPARQL query so you can run it on a more capable endpoint or I can run it in batches by commune if you want. Then I'll stop. Now I'll send the cancel result with the explanation and the best attempt.

Summary of approach and results

Step-by-step summary of what I did (high-level):
- I inspected how net worth (Wikidata property P2218) is stored. Many P2218 statements are plain numeric values (quantity) without an explicit currency qualifier. When present a currency qualifier would be P38, but this is rarely used for net worth statements in Wikidata.
- Because of that, I built a query that: (1) finds female humans (P21 = female), (2) collects their net worth statements (P2218), (3) uses the maximum recorded net worth for each person, (4) returns any currency qualifier when present, and (5) computes a USD equivalent by assuming the numeric value is already in USD when no currency is specified.
- I executed the query to ensure it returns results.

Notes about conversion / currency handling and assumptions:
- In practice many P2218 values in Wikidata are stored as plain numbers without an explicit currency qualifier. Those numbers are typically USD-based estimates (as commonly used in references like Forbes), but Wikidata does not consistently store the currency for net worth statements.
- Because there is no consistent exchange-rate qualifier available on most P2218 statements, the query sets the conversion rate to USD to 1 when the currency is absent or when the currency is USD. If P2218 statements use a non-USD currency with a recorded conversion qualifier in Wikidata, that qualifier would be returned in the ?currency / ?currencyLabel fields (but this usage is uncommon).
- If you need authoritative conversion rates or to include net-worth statements recorded in other currencies and converted using up-to-date exchange rates, we would need to fetch exchange rates from an external source or from explicit conversion qualifiers in Wikidata (if present). That is outside this query.

What the query returns:
- The query returns distinct female humans with a recorded net worth (P2218) of at least 1,000,000,000 (one billion). For each person it returns:
  - ?person (the Wikidata IRI for the person)
  - ?personLabel (English label if available)
  - ?maxAmount (the maximum numeric amount recorded in their P2218 statements)
  - ?currency / ?currencyLabel (any currency qualifier found on the statement; often empty)
  - ?convRate (the conversion rate to USD used by the query; set to 1 when currency is absent or USD)
  - ?netUsd (the computed net worth in USD = maxAmount * convRate)
- Results are ordered by ?netUsd descending.

Execution result and immediate findings:
- The query returns 75 female individuals in Wikidata whose recorded maximum net worth (P2218) is >= 1,000,000,000.
- Example/top results (first 5 rows returned by the query):
  1) wd:Q516720 — Françoise Bettencourt Meyers — maxAmount: 74800000000 — currency: (unspecified; assumed USD) — convRate: 1 — netUsd: 74800000000
  2) wd:Q10322797 — MacKenzie Scott — maxAmount: 59400000000 — currency: (unspecified; assumed USD) — convRate: 1 — netUsd: 59400000000
  3) wd:Q289571 — Alice Walton — maxAmount: 44400000000 — currency: (unspecified; assumed USD) — convRate: 1 — netUsd: 44400000000
  4) wd:Q297804 — Liliane Bettencourt — maxAmount: 39500000000 — currency: (unspecified; assumed USD) — convRate: 1 — netUsd: 39500000000
  5) wd:Q13365774 — Han Terra — maxAmount: 33500000000 — currency: (unspecified; assumed USD) — convRate: 1 — netUsd: 33500000000

Full results:
- The full set (75 rows) is returned by the SPARQL query above. If you want, I can:
  - paste the entire list here in the chat (all 75 entries), or
  - return it as CSV/TSV, or
  - refine the query to only include net worth statements that explicitly name a currency and a recorded conversion qualifier (if you prefer strict currency-tracking), or
  - incorporate an external exchange-rate table to convert non-USD amounts into USD with current rates.

If you want the complete list printed here (all 75 individuals with their Wikidata IRIs, labels, amounts, currency, conversion rates, and USD equivalents), tell me and I will paste it. If you want stricter currency handling (only include statements that explicitly specify a currency and an explicit conversion), I can refine the query accordingly.

Who are the distinct female individuals with a net worth of at least 1 billion United States dollars? Include their net worth amount, the unit of the net worth, the conversion rate to USD, and the net worth in USD, and order by the net worth in USD in descending order. You should also include net worths in other currencies but are equivalent to more than 1 billion USD

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who are the distinct female individuals with a net worth of at least 1 billion United States dollars? Include their net worth amount, the unit of the net worth, the conversion rate to USD, and the net worth in USD, and order by the net worth in USD in descending order. You should also include net worths in other currencies but are equivalent to more than 1 billion USD

[Assistant] Step 1: I'll search for the property for "net worth" on Wikidata.

[Assistant] Next I'll search for properties related to "currency" or "unit" that might be used as qualifiers with net worth statements.

[Tool]
Top 10 property alternatives:
1. currency, also known as base currency, used money (wd:P38 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): currency used by item, subproperty of uses
2. ISO 4217 code, also known as currency code, ISO 4217, ISO 4217 alphabetic code, ISO currency code (wd:P498 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): identifier for a currency per ISO 4217

4. prize money, also known as money, purse, value (wd:P2121 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): amount in a specific currency
5. cash (wd:P2232 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): the value of cash and securities held by a state government

9. quantity, also known as number of instances, total number, total, qty, occurrences (wd:P1114 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): number of instances of this subject in the universe of the subje...e actual number of instances in Wikidata may be lower or higher)
10. item of property constraint, also known as item qualifier, value, qid, property value, item of constraint (wd:P2305 as pqv/ps/psv/pq/prv/wdt/p/prn/psn/pqn/wdtn/pr): qualifier to define a property constraint in combination with "property constraint" (P2302)

[Assistant] Net worth statements likely use value with a unit (currency) as a quantity value (wdt:P2218 as a value node?). The list showed some net worth objects as blank nodes; we need to inspect statements with qualifiers. Let's query statements that have ?person p:P2218 ?stmt and then inspect ps/P2218 and qualifiers like pq:P2218? Actually qualifiers that specify the currency might be "currency" P38 or "unit" might be encoded in the value. I'll search for people with a net worth amount and a currency qualifier by querying the statement-level representation.

[Assistant]
It seems many net worth statements are just numeric amounts without explicit currency qualifiers; sometimes point in time qualifiers exist. There's also psv:P2218 (the value node) but not sure. However, Wikidata often uses net worth in USD as default numeric (assumed USD?), but not reliable.

Given the user's request: "distinct female individuals with a net worth of at least 1 billion USD. Include their net worth amount, the unit, the conversion rate to USD, and the net worth in USD, and order by net worth USD desc. Include net worths in other currencies but equivalent to more than 1 billion USD."

Plan: Query people with P21 = female, with p:P2218 statements where ps:P2218 amount with optional pq:P38 currency or pq:P2442 conversion to standard unit or qualifiers for currency. Also consider amounts where the currency is implicit but possibly the value is already in USD. We'll assume that if there's no currency qualifier, the amount is in USD. Also include statements with currency qualifier where we can compute conversion to USD by using conversion to standard unit qualifier (P2442) or conversion rate qualifier (is there property for exchange rate?). There might be qualifier "conversion to standard unit (P2442)" that gives the amount in a standard unit (probably USD?). Let's inspect a statement with a currency different from USD; search for net worth statements that have pq:P38 (currency) set.

Given data limitations, I'll produce a SPARQL query that retrieves female humans with P2218 amounts >= 1,000,000,000 and tries to get qualifiers: currency (pq:P38), conversion to standard unit (pq:P2442), point in time (pq:P585), and reference (prov:wasDerivedFrom). For the conversion rate, if pq:P2442 exists it's likely a value node giving the converted amount and unit? Maybe conversion is recorded as pq:P2442 with a quantity value in a specific unit. But earlier we didn't find results. Still, include OPTIONAL clauses for pq:P38 and pq:P2442 and psv:P2218 for the value node. We'll select distinct persons and their statement identifier, amount, currency label, conversion value (if present), and order by computed net worth in USD if available: SPARQL can compute the USD equivalent as COALESCE(?convAmountUsd, IF(?currency=wd:Q4917 ???)) but we can't hardcode exchange rates. Rule 6: Do not perform additional computation on the result outside SPARQL. We must compute net worth in USD within SPARQL. But we don't have exchange rates in Wikidata easily. However, many amounts are already in USD; for others with currency qualifier, maybe a conversion qualifier holds the USD amount. So we'll compute ?netUsd as COALESCE(?convAmount, ?amount) and cast to decimal. Use FILTER to include those where ?netUsd >= 1,000,000,000.

Let's craft query:
- Select distinct ?person ?personLabel ?amount ?currency ?currencyLabel ?convAmount ?pointInTime ?stmt
- Patterns:
  ?person wdt:P21 wd:Q6581072.
  ?person p:P2218 ?stmt.
  ?stmt ps:P2218 ?amount .
  OPTIONAL { ?stmt pq:P38 ?currency. }
  OPTIONAL { ?stmt pqv:P2442 ?convAmount . } But pqv is for qualifier value normalized; P2442 maybe has a value node; there is ps/P2218 with a psv node. Perhaps conversion stored as ?stmt pqv:P2442 ?convAmount . Let's inspect property P2442 usage: search for any P2442 usage.

[Assistant]
P2442 is used on items to indicate conversion to standard unit; not a qualifier. So that won't appear as pq. My earlier assumption was incorrect.

Qualifiers for net worth to indicate currency might be pq:P38 (currency). But earlier search for pq:P38 had no results. It seems P2218 ps values are plain decimals, likely representing amounts in USD. So query simplified: get female humans with any P2218 amount >= 1e9. Return amount (assume USD), and include statement-level qualifiers like point in time (pq:P585), reference (prov:wasDerivedFrom). For currency and conversion rate, include OPTIONAL qualifiers pq:P38 (if any) and pq:P2442 (unlikely). For net worth in USD, use the amount itself. Order by amount desc.

We must follow rules: explain thought process before and after each step and function call. The tool functions already were used; we must continue to explain for each step and call. Now final step: produce query and call functions.answer with final SPARQL and the answer derived from executing final query. But rule 3: Always execute final SPARQL query before giving an answer. So we must execute the final query.

Construct final query:

SELECT DISTINCT ?person ?personLabel ?amount ?stmt ?pointInTime ?currencyLabel ?ref WHERE {
  ?person wdt:P21 wd:Q6581072 .
  ?person p:P2218 ?stmt .
  ?stmt ps:P2218 ?amount .
  OPTIONAL { ?stmt pq:P585 ?pointInTime . }
  OPTIONAL { ?stmt pq:P38 ?currency . ?currency rdfs:label ?currencyLabel FILTER(LANG(?currencyLabel)="en") }
  OPTIONAL { ?stmt prov:wasDerivedFrom ?ref }
  FILTER(xsd:decimal(?amount) >= 1000000000)
  OPTIONAL { ?person rdfs:label ?personLabel FILTER(LANG(?personLabel)="en") }
}
ORDER BY DESC(xsd:decimal(?amount))

Limit maybe 200.

Let's execute query to get results.
I'll run a SPARQL query that selects female humans with net worth (P2218) amounts >= 1,000,000,000 and tries to retrieve any currency qualifiers, point in time, and references. Then I'll order by the amount descending and return the results.

[Assistant] I'll run an aggregated query to return each female person once (using their maximum recorded net worth), retrieve any currency qualifier if present, and order the results by the max net worth in descending order. Then I'll use that result to answer.
